SIGNAL-LAMP.

Specification of Letters Patent.

Patented Aug. 11, 1914.

Application led September E), 1908. Serial No. 452,295.

To all whom it may concern:

Be it known that I, FRED Wnlxle, a citizen of the United States, residing at the city of New York, borough of Bronx, in the county and State of New York, have invented certain new and useful Improvements in Signal-Lamps, of which the following is a full, clear, and exact specification.

My invention relates to improvements in signal lamps, and the same has for its object more particularly to provide a signal lamp having a plurality of signal glass holders therein which are adapted to be thrown individually into position between the lens and the lamp.

Further, said invention has for its object to provide a signal lamp having a plurality of signal glass holders which are so constructed and arranged that the shifting of one of the signal glass holders into operative position will automatically lock the remaining signal glass holder or holders in inoperative position.

Further, said'invention has for its object to provide a supporting means for the signal glass holders and the automatic locking device therefor, which may be bodily set into a lamp and secured thereto in order to maintain the same in position to bel operated from without the lantern casing.

To the attainment of the aforesaid objects and ends my invention consists in the novel det-ails of construction, and in the combination, connection and arrangement of (parts hereinafter described, and then pointe out in the claims.

In the accompanying drawings forming part of this specification, wherein like numerals of reference indicate like parts, Figure 1 is a side view partly broken away and in section, showing one form of signal lantern constructed according to and embodying my invention. Fig. 2 is an enlarged detail horizontal sectional view showing the signal glass holders and the locking means therefor in top view; Fig. 3 is an enlarged detail side .view showing the supporting means and locking device for the signal glass holders, one of said signal glass holders being shown in operative position, and the other locked to its inoperative position; Fig. 4 is a sect-ion taken on the line 4-4 of Fig. 3, looking in the direction of the arrow, and Fig. 5 is an end view of the parts shown in side view at Fig. 3.

`of the lantern.

I n said drawings 10 designates a lantern casing of usual general construction projvided with a sliding door 11, and at two of its sides with lenses 12 l2 mounted in cones 13 13 arranged at right angles to each other, and 14 denotes a lamp supported in the base To one side of each lens cone upon the inner surface of the lantern casing 10 is secured a bracket 15 having a centrally located upwardly extending rigid supporting arm 1G provided at its upper end with a bearing 17. To each side of said Arigid supporting arm 16 are arranged upwardly projecting short arms or bearings 19 19 denote signal glass holders each having an arm 20 extending therefrom which arranged intermediate one of the bearings 1S 18 and the arm 16, and pivotally mounted upon a screw or rivet 21 passing through both of said arms 20, 20, the bearings 18, 1S and the arm 16. To the other or `projecting ends of the arms 2O 2() are pivotally secured links 22 22 having their ends bent at right angles thereto to form finger portions 23 23. The extreme ends of the arms 201 20 are provided with semicircular recesses to receive the free ends of springs 24, 24 which are secured at their lower ends to the bracket portion 15. The springs 24 24 are provided adjacent to their free ends with offset portions 25 25 which are adapted to engage the recessed free ends of the arms 20 20 in order to maintain the signal glass holders 19 19 to their operative or inoperative positions.

27 denotes a locking device consisting of a substantially rectangular oscillating link member 28 which normally embraces the arms 20 2O of both signal glass holders when the same are raised or adjusted to their inoperative positions. The said link member is pivotally suspended from its upper edge upon a screw 29 secured in one end of the bearing 17 on the arm 16, andhas its lower end split, and its ends 30 30 inclined downwardly toward each other, and separated only enough to receive one of the arms 20 of the signal glass holders at one time `which is adapted to rest upon the inclined portion or stop 31 of the bracket 15.

32 32 denotes housings which are secured to the outer surface of the lantern casing and inclose the projecting portions of the bracketsl 15 and parts carried thereby. Said one of the links 2222 upwardly into the housing32 by means of its linger portion 23 thereby elevating the projecting end of one of the signal glass arms connected thereto," and Vcausing the forward end of said arm which carries thesignal glass to move downwardly, until its lower edge engages the inner 'inclined' edge ot' the link 28 and passes into the opening or split in said link and contactswith the inclined surface or stop 31 on the bracket 15', thereby limiting the downward movement of said arm and the lens holder carried thereby. As soon as the Veo arm 20 has come into engagement withsaid inclined portionor stop 31 the colored signal glass will be in position intermediate the lamp and the lens of the lantern and impart to the light projected through the lens the color desired. By the movement of one signal glass holder into operative position inl termediate the lamp and the lens, the re-- inaining signa-l glass holder will beheld to its inoperative position, this result being due to the tact 'that the slit in the bottom of the link`29J is only wide enough to accommodate the arm of one glass holder at a time. As the arm o'l' one glass holder enters said slit the link 28 will be moved to one side or the other, and in so doing one of the inclined ends 30 of said link will be brought into contact with the lower edge of the arm 2O of the inoperative signal glass holder and prevent the same being lowered until the glass holder then in operative position has been treed of its engagement with the slit in the link, and again raised to its inoperative position.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

l. In a signal lamp the combination of a bracket, a vertical member thereon, signal glass holders pivotally mounted on said member, means for actuating said signal glass holders, a member pivotally mounted on said vertical member and embracing said signal glass' holders intermediate ofV their ends for locking one of said signal glass holders in inoperative position as the other of said signal glass holders is moved into operative position, and means carried by said bracket for positively maintaining said signal Vglass holders to their operative and inoperative positions,substantially as specified. Y

2. In a signal lamp the combination of a bracket, a vertical member thereon, bearings on saidbracket, signal glass holders pivotally supported upon said bearings, mea-ns for actuatingV said signal,v glass holders, Ia member pivotally lmounted on said vertical member and embracing `said signal glass holders intermediate of their ends for locking one of said signal glass holders in inop erativeposition as the other of said signal glass vholders is moved into operative position, and means-carried by said bracket for positively maintaining said signal glass holders to their operative and inoperative positions,substantially as specified.

3. In a signal lamp the combinationcof a bracket, a vertical member` thereon, bear-` ings on said bracket positioned on opposite sides ot' said member andspaced therefrom,
